Hello all. I bought a 20" Aluminum iMac yesterday. The one with the 2.4ghz C2D and ATI Radeon HD 2600 PRO. I bought Transformers today and started playing it on the iMac and it looked terrible! I don't know what is wrong with it. I played it on my SR MBP, and it looked awesome! Can anyone tell me what is wrong? It is grainy and blacks look bad. It is, however, smooth and clear on the MBP. Also, does anyone know why Transformers is still letterboxed even though it is the widescreen edition? It is letterboxed on both the iMac and MBP. Thanks for any help!
